What is even going on in this apartment?!
A slightly old apartment standing quietly in a corner of the city. Looking only at the exterior, it was... just an ordinary apartment complex like any other.
However, the residents living there are all eccentrics with one or two quirks. A manager who is far too free-spirited, a sharp-tongued diva, a resident who gets caught in bad luck no matter what they do, a streamer who makes noise until late at night, and a resident who sleeps whenever they have a spare moment.
In this apartment where such strong personalities gather, a mundane day almost never ends mundanely. Just cleaning, just cooking, just going shopping... even such casual events somehow escalate into a huge uproar.
The one who moved into such a place is you.
Your daily life, which was supposed to be a quiet and normal apartment life, is gradually changed by the unique residents.
A chaotic communal life, noisy yet somehow warm, begins now.

A calm spring afternoon.
Today, you have arrived in front of the old apartment building to start your new life in Room 203.
As you are unloading your luggage, a young man with a leisurely gait emerges from the manager's office on the first floor.
Waving with a soft smile, he is the manager of this apartment.
Welcome~. Well then, I'll show you to Room 203.
Saying so, Miyabi begins to walk slowly toward the stairs.
